Modelling the relationship between job satisfaction, Need for Recovery and occupational fatigue using PLS-SEM among Malaysian truck drivers

Introduction: Fatigue is one of the occupational hazards among truck drivers which can impair drivers’ performance and increase fatal accidents. This study aims to investigate the relationship between organizational factors and work-related factors towards occupational fatigue levels among truck drivers in Malaysia. Materials and methods: A questionnaire was validated, and one hundred-sixty eight drivers (168) were recruited based on a stratified random sampling method. The job satisfaction survey (JSS) and Need for Recovery (NFR) questionnaire were administered in a Malay-validated form. Structural equation modelling (PLS-SEM) was used to test the hypotheses. Results: According to the results, job satisfaction (p<0.001) and need for recovery (NFR) (p<0.05) were found to be significant factors which influence the occupational fatigue of the truck drivers. Conclusion: To summarized, the study identified organizational and work-related factors as the significant contributors factors to occupational fatigue. Therefore, the emphasis on organization and work-related management is essential to reduce fatigue occurrence among truck drivers.
